` i e i p n i MACHINE ron STAMPING LACE-PAPER.

i i l The Schedule referred to :in these `Ilfiiel'lter's Patent vmakingvpari: of the same `To all whom' itouay concern y A Be it known thatI, Alimuosn GIRAUDAT, ofthe city, county, and State of NewYork, have invented a new and improved Machine for Stamping Lace Paper; andiI do hereby declare that the following is a full, clear, and exact description thereof, which. will en-` `able others skillediuthe artyto make and use the same, reference being had to the accompanying drawings ibrming part of thisSpecticatiOn. Figure 1 representsia "plan or: top view of my machine for stamping lace paper." 3 'e e Figure 2 is a sideelevation, partly in section, of the` `sa-me. i i y Figure 3 is a vertical transverse section of the saine,

taken on the plane of the line x x, fig. 1. e Figure 4 is ade-tail vertical section of the same, takenon the planeof the line y y, fig. 1. Figure 5 is a detail front View of part of the same. l `Similar letters of referenceindicatecorresponding parts. I This invention' relates to a newmachiue` for stamping lace-paper, either in long strips or circular pieces,4 and has for its object` toledo" away with the ordinary tedious manual process? and to permit the employment i upon the same piece of a number of hammers. Therei, by the process of stamping will be greatly facilitated,

and less labor will be requiredfor the purpose.

The'inventiou consists-.- i 7 First, in such ageneral arrangement of dies, holdstamping can he rapidly carried ou. 4

i The invention cpnsists also in the applicatiolpto the e hammers cfa series of adjustable springs, by means of 1 which the power of the hammer may be regulated at iiivill. l I

The inventionfconsists further in providing a suspended'guide-spring by which theyhammers are held in any desired position, which is a very important item` in circular' work. z i

Finally, the invention consists in suspending the Vhammers from pivoted. levers, so that the said hammers can be swung on the leversfinto any desiredpositio'n. y y

A, in the drawings, represent the frame of my improved stamping-machine. `1t is `represented as supporting two independent machines, one for straight, the other for circular work. Both these machines are necessary fora perfect understanding of my invention. Still "they can be used separately.

i The machine for stamping circular paper contains various devices which are notnece'ssary for the other. I shall, therefore, rst describe the circularmachine. The frame A carries a horizontal4 shaft or rod, a, which serves for four, more or 'less-levers, B B, which havehooks b b at tlleiiwii'cntem-,wjhe their rear y i ALetters YPatent No. 100,749, dated Mai-rch 15, 1870.

ends extend close to a drum ors'haft, G, which is hung in then-ame.

The drumy C has a series of projecting arms, c c, which, when the drum is revolved strike the rear ends of the levers -B and oscillatethe same. v

The'arins' are set upon the `drum iu spiral rows, to move the levers in alternate succession, v To the frame A are1 secured springs fD, which- 'are connected with the levers B to counteract the armslc. Thus, as the arms by their action elevate the front ends of the levers, the springs will tend to draw' the said ends dowuimmediately after the-levers are liberated from the arms. i y 'i v e The springs are fastened" to or connected with a pivoted plate, E, which is by means of a rod, (Liconnected with a treadle, F. y

Bydepressing the treadle the plateE will be swung means of the treadle the power of the springs can be regulated at will. From the hooks b b are suspended a series of rods, G G, tothe lower` ends of which the (lead) hammers 1 e e are secured. .e

For this purpose sockets fare formed at the lower ends of the `rods G, sov that the Shanks of the hammers may be tted into and locked in them by means The front ends of the levers B are all in a straight line, or may, at least, be so in all cases. p

Under the hammers is supported on a fixed bed, H, the die I, which is of semicircular or semi-annular or -A other suitable form, containing in form of prje`c'ti'E- M the ornamental design to be cnt through the paper.

" The rods G of the hammers pass through eyes or This spring has handles at its ends so that it can be bent into any suitable form, to thereby hold the hammers in the desired position.

Rods h h, which are suspended from arms c' of the The paper to be stamped is placed upon the die and is held in place by a spring lever, L, which presses it upon au elevated part of the bed H.

After the paper has been placed upon the die the drum C is rotated by hand or machinery to oscillate the levers B and move the hammers up and down.,

The force of' the hammers is determined bythe power of the springs D, which is regulated by the treadl'e F. 4 f

The hammers are guided over the proper places by i fd means of the spring J, which can be bent or moved in either direction forthe said purpose.

c It' but one single hammer is to be used the spring can be taken off and a plate, M, used in its place, in the manner indicated'in iig. 5.

A plate, N, can he pivoted to the frame and connected with a handle to hold the levers up out of action when not used.

The machine for stamping straight strips of paper is constructed substantially on the sameprinciple. It consists of a drum, G', having arms c', and acting upon levers B', which are connected with springs D.

The tension of the latter can be regulated by means of a plate, E', and treadle F, in the manner above described.

The hammers e nre, however, not secured to separate rods, but may be fastened direct-ly to the ends of the levers B', as shown.

The die 1' rests upon a bed, H', which has a snitble clamp, L', for retaining the paper upon the die.

vThe bed H is not stationary as on the circular machine, but is placed upon a supporting block, O', on

which itcan slide. Thus, as the hammers are merelyy worked up and down by the rotation of the drum O', the paper with the dies is moved backward and forward under the same, to bring its surface under theirV action.

On the circular machine the die is stationary while the hammers are adjustable.

A lerer,N, with handle j is also employed for holding theY hammers on" the dies.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent 1. The combination of the stationary or movable dies with-the paper holders L or L', and hammers eor e', the hammers being operated to stamp the paper on the dies, substantially in the manner herein shown and described.

2. The springs D connected with the leversB or B', that operate the hammers, the said springs being connected with a lever to have their tension regulated as set forth.

3. .The spring J suspended from the fram'e A and provided with the loops g to serve as guides for the hammer Shanks or rods G, as set fort-h.`

4. The hammers e suspended from the pivoted 1evers B inY such manner that they can be swung above the fixed dies, as set forth.

5. The die I made adjustable with its supportingbed H' to guide the paper under the hammer, as set forth. A
